Recently I have faced the similar issue in Azure Windows Server 2012 r2 . Tried all option with and without Anaconda but none of them helped. After lot of findings I found that mfplat.dll was missing which is related to Window Media Service.

Hence you have to manually install the features so that you can get dll related to window media service.

1.Turn windows features on or off

2.Skip the roles screen and directly go to Feature screen

3.Select "Desktop Experience" under "User Interfaces and Infrastructure"

After this all required dll of media services for opencv would be available.

So if you are planning to run your code in cloud(Window Server) then please dont forget to select Desktop Experience feature.

Comments
  • The latest supported version of python in OpenCV is 3.5 not 3.6
  • @kmario23: I tried with Python 3.5.0 and I still get the same error.
  • Check out the answer of @tientuyen07, it works for me. For python3.7.0 on Windows10.
  • AN UPDATE: opencv3.2.0 with opencv_contrib binaries for Python 3.5 and 3.6 are now available for download from the unoffice site. Look for entry consists of +contrib in the file name. For example, opencv_python‑3.2.0+contrib‑cp35‑cp35m‑win_amd64.whl.
  • Requirement 'opencv_python-3.2.0-cp36-cp36m-win_amd64.whl' looks like a filename, but the file does not exist
  • It looks that opencv 3.2 for python 3.x are removed after my UPDATE. You may use opencv 3.3.
  • A note for those who don't know, like I didn't: the cp in filenames there stands for CPython, so the number after that is your Python version.
  • There are several issue about this question, but I find it's platform is not Windos10 + Python3.7.0. And your answer is works for me. Thanks a lot.
  • worked for me. I had installed opencv-python and some else, but this was the final thing.
  • it works great... after spending 4 hrs, came to this post... helped me alot. currently using Anaconda3-4.1.1-Windows-x86_64 with Python 3.5.2 :: Continuum Analytics, Inc.
  • It worked for me on Windows Server 2012. Thanks a lot
  • thanks for this answer! You saved me a lot of time and it worked perfectly on my Win2012R2!
